Part of cycle lane, hard ground comprising bitumen, primarily (9)
I believe the answer is:
handlebar
'part' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'cycle lane hard ground comprising bitumen primarily' is the subsidiary indication.
'cycle' indicates an anagram.
'ground' is an anagram indicator (grind the letters ).
'comprising' indicates putting letters inside.
'primarily' says to take the initial letters.
The first letter of 'bitumen' is 'b'.
'lane' anagrammed gives '[lane]'.
'hard' anagrammed gives '[hard]'.
'[lane]'+'[hard]'='handlear'
'handlear' going around 'b' is 'handlebar'.
'of' is the link.
Can you help me to learn more?
(Other definitions for handlebar that I've seen before include "Upwardly curled facial growth" , "part of a cycle" , ""Support for the cyclist"" , "Type of moustache - on bicycle" , "guide for bikers" .)
